When a member is said to be "connected" to another member, this means that the member may be directly connected to the other member or that intermediate members may also be present. In the illustrated embodiment, the directions indicated up, down, left, right, front and back, etc. are relative, and are used to explain that the structures and movements of the various components are relative in this case.These representations are appropriate when the elements are in the positions shown in the figures. However, if the description of the positions of the elements changes, it is obvious that these representations will change accordingly.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of the present invention. The terminology used herein is used only to describe particular embodiments and is not intended to limit the present invention. As used herein, the term "and / or" includes all combinations of one or more of the listed elements together.

[0030] As shown in [Fig.l], a three-dimensional schematic view of the foldable magnetic support device of the present invention is in the folded state. The foldable magnetic support device of the present invention comprises a magnetic base 10, a first support unit 20, a first pivoting unit 30, a second pivoting unit 40, and a second support unit 50. The magnetic base 10 has a magnetic area 11 and a support base 12. The magnetic base 11 and the support base 12 are respectively located on opposite sides of the magnetic base 10. A magnet 13 is disposed at the location of the magnetic area 11 inside the magnetic base 10. In [Fig.l], the position of the magnet 13 is shown imaginarily, while in [Fig.4], the actual shape is illustrated. Thus, the magnetic base 10 can magnetically fix a mobile phone. The magnetic base 10 is rotatably installed on the first support unit 20. In [Fig. 2], the magnetic area 11 faces outward. In [Fig. 3], the magnetic base 10 is rotated 180 degrees, so that the support base 12 faces outward. The support base 12 is used to install a magnetic wireless charging head. In use, the magnetic wireless charging head is used to magnetically fix the mobile phone, and the mobile phone can then be charged by connecting to a power supply. The first pivoting unit 30 is pivoted on the first support unit 20 and is located away from the magnetic base 10. The first pivoting unit 30 has a first extension member 31 protruding at a middle position. The second pivoting unit 40 has a second extension member 41 protruding at a middle position.The second extension member 41 and the first extension member 31 are placed end to end and can both rotate along the same axis. The second pivot unit 40 is pivotally connected to one side of the second support unit 50. The second support unit 50 is a long and narrow structure. By utilizing the structural features of the first pivot unit 30 and the second pivot unit 40, not only can the angle between the first support unit 20 and the second support unit 50 be adjusted, but also the relative position between the two can be changed, thereby providing a variety of hands-free modes for using the mobile phone attached to the magnetic base 10.

[0031] A brief description of each component is presented below. As shown in Figures 2 and 3, the magnetic base 10 is rotatably installed on the first support unit 20, and the rotation direction is perpendicular to the first support unit 20, so as to switch the magnetic area 11 or the support base 12 to face outward. Therefore, the magnetic base 10 and the first support unit 20 are provided with a positioning mechanism for fixing the switching position. [Fig. 4] is an exploded view of the magnetic base. A shaft 14 protruding from an outer wall of the magnetic base 10 is installed in a shaft hole 21 of the first support unit 20, and the latter is fixed to the shaft 14 by a screw 22.A spring 23 is fixed to the periphery of the shaft 14, so that the magnetic base 10 can not only rotate at the shaft hole 21, but also move axially a short distance without detaching from the shaft hole 21. The first support unit 20 is connected to the outer wall of the magnetic base 10 by a carrier base 24.

[0032] A positioning bump 15 is provided on the outer wall of the magnetic base 10 adjacent to the shaft 14, and the supporting base 24 has a positioning groove at a corresponding location. When an external force greater than the spring 23 is applied to the magnetic base 10, the magnetic base 10 can rotate and move axially a short distance. When the magnetic base rotates on the carrier base until the positioning bump 15 is located in the positioning groove 241, the relative positions of the first support unit 20 and the magnetic base 10 are fixed. [Fig. 2] shows a mode of use in which the magnetic area 11 faces outward, and [Fig. 3] shows a mode of use in which the support base 12 faces outward.

[0033] In the present embodiment, the main body of the magnetic base 10 is ring-shaped and has two opposite sides. The magnetic area 11 and the support base 12 are respectively located on the opposite sides. The magnetic area 11 is a flat surface, and a magnet 13 is placed inside the magnetic base 10 at the location of the magnetic area 11, so that the magnetic area 11 exerts a magnetic attraction force. Referring to [Fig. 4], the structure of the magnetic area 11 forms an accommodating groove 16 in the ring-shaped structure of the magnetic base 10. The accommodating groove 16 is for accommodating the magnet 13. Furthermore, a cover sheet 17 is provided. The cover sheet 17 may be a soft pad or a thin pad, the cover sheet 17 is adhered to the magnetic base 10 and seals the accommodating groove 16.The exposed flat area of ​​the cover sheet 17 is the magnetic area 11, as shown in [Fig. 1]. Thus, the magnetic area 11 exerts a magnetic attraction force. As shown in [Fig. 3], the support base 12 is surrounded by a ring-shaped wall 121 to form a receiving area 18. The receiving area 18 can receive a magnetic wireless charging head. Furthermore, the ring-shaped wall 121 has a main body and two sets of auxiliary walls 122 which are higher than the main body of the ring-shaped wall 121. The inner wall of the auxiliary walls 122 has raised strips 123. The auxiliary walls 122 are elastic to ensure slight deformation, thereby increasing the final strength after the magnetic wireless charging head is placed in the receiving area 18.

[0034] The first support unit 20 is a multi-part structure. One side forms an arc-shaped support base 24 for installing the magnetic base 1, and the other side of the structure is used for pivoting the first pivoting unit 30, the first support unit 20 can rotate according to a pivot shaft of the first pivoting unit 30 to adjust the tilt angle of the first support unit 20.

[0035] Referring to [Fig.5], the first pivot unit 30 is a T-shaped pivot body. The pivot shafts 32 extending from both sides are pivotally connected to the first support unit 20 so that both can rotate relative to each other. The first pivot unit 30 has a first projecting extension element 31 in its center. The second pivot unit 40 is also a T-shaped pivot body. The pivot shafts extending on both sides are connected to the second support unit 50 so that both can rotate relative to each other. The second pivot unit 40 also has a second projecting extension element 41 in the middle position. The second extension element 41 abuts against the first extension element 31 and both can rotate about the same axis. Thus, the first pivot unit 30 provides a specific axial rotation angle of the first support unit 20. The second pivot unit 40 provides a specific axial rotation angle of the second support unit 50.Furthermore, the first extension member 31 and the second extension member 41 can rotate relative to each other along the same central axis. Therefore, the relative position of the first support unit 20 and the second support unit 50 can be adjusted by nearly 360 degrees to meet the needs of the user.

[0036] In the present embodiment, the various pivoting positions, including the pivoting junction between the first support unit 20 and the first pivoting unit 30, the end-to-end junction between the first extension member 31 and the second extension member 41, and the pivoting junction between the second pivoting unit 40 and the second support unit 50, are all provided with a rotation positioning mechanism, and the rotation positioning mechanism maintains the relative position of the two components after adjustment by engaging a toothed surface. As shown in [Fig. 5], the rotation positioning mechanism at the junction between the first extension member 31 and the second extension member 41 is illustrated. The mechanism here comprises a toothed surface 42, a screw 43, and a spring 44.The corresponding surface of the first extension member 31 is also provided with a toothed surface (not shown in the figure), so that both members can rotate; and after rotation, the toothed surface is used to position one relative to the other. Since this mechanism is similar to the conventional mechanism, it will not be described in detail.

[0037] In addition, in addition to the side of the second support unit 50 for the pivotal connection of the second pivot unit 40, in the present invention, the side of the second support unit 50 away from the pivot junction is also provided with a clamping unit 60. The clamping unit 60 is used for clamping a plate-shaped object, thus providing various modes of use. As shown in [Fig. 5], the clamping unit 60 comprises a fixed clamping member 61 and a movable clamping element 62, the fixed clamping element 61 is located on the side of the second support unit 50 opposite the pivot joint. The movable clamping element 62 is L-shaped, extends partially inside the second support unit 50 and can move linearly away from the fixed clamping element 61. The clamping unit 60 provides the clamping function by the fixed clamping element 61 and the movable clamping element 62, and there are many ways to drive the movement of the movable clamping element 62, such as driving the movable clamping element 62 by rotating a screw. However, the present invention adopts a simpler method. In the present embodiment, the clamping unit 60 also comprises an elastic body 63, and the elastic body 63 is a spring. The elastic body 63 is located in the second support unit 50 and is in contact with the movable clamping member 62. The elastic body 63 maintains the tension of the clamping. In the absence of external force, the elastic body 63 is responsible for causing the movable clamping member 62 to move to contact the fixed clamping member 61. Furthermore, the main structure of the movable clamping member 62 is an L-shaped metal piece 621. Since the structures entering the second support unit 50 are all made of metal, they can not only maintain better rigidity but also have an appropriate weight.Thus, when the second support unit 50 is used as a base, the stability when placed on the desktop is improved.

[0038] Furthermore, to facilitate operation, the clamping unit 60 is also provided with a guide groove 64 and a pulling member 65. The guide groove 64 is located in the second support unit 50 and its upper surface penetrates the wall. The pulling member 65 is partially combined with the metal part 621 of the movable clamping member 62 located in the second support unit 50 through the guide groove 64. When the pulling member 65 is pulled, the movable clamping member 62 can move synchronously, which allows the operator to easily push the movable clamping member 62 to facilitate the clamping of the plate-shaped object by the movable clamping member 62 and the fixed clamping member 61.

[0039] Next, a description of the mode of using various hands-free mobile telephones of the present invention will be provided.

[0040] As shown in [Fig. 6], the second support unit 50 does not clamp any object. The second support unit 50 is placed on the desktop as a base. Since the movable clamping member 62 is partially made of metal, it provides considerable weight which is more stable. Then, the first support unit 20 is rotated relative to the first pivoting unit 30 so that the first support unit 20 is in an inclined state, and then the magnetic area 11 of the base ma magnetic base 10 is used to directly fix a mobile phone 70 magnetically. By means of the magnetic fixing, the mobile phone 70 can be easily adjusted for vertical or horizontal use according to the user's needs. [Fig. 7] illustrates another mode of use of the present invention. If a user wants to use a mobile phone while charging it, the user can first rotate the magnetic base 10 by 180 degrees, and then install a magnetic wireless charging head 80 on the support base 12 at the receiving area 18. The magnetic wireless charging head 80 magnetically attracts the mobile phone 70, so that the mobile phone 70 can be used while standing on the desktop. In addition, the mobile phone 70 can also be adjusted to a horizontal use mode by rotation.

[0041] As shown in [Fig. 8], for a hands-free selfie mode, the first pivot unit 30 and the second pivot unit 40 must be adjusted so that the first support unit 20 and the second support unit 50 remain aligned. The second support unit 50 is held in a linear shape, and the magnetic base 10 magnetically attracts the mobile phone 70, so that selfies can be conveniently taken with the mobile phone 70. Of course, the first support unit 20 can also be adjusted to different tilt angles to facilitate taking selfies from the best angle.

[0042] As shown in [Fig.9], the clamping unit 60 is used to clamp a plate-shaped object 90. The plate-shaped object 90 may be a table or a meal tray at the back of the seat in an airplane, a high-speed rail, a train, or other mass transit system. The clamping unit 60 clamps the plate 90 using the movable clamping member 62 and the fixed clamping member 61, and adjusts the first pivoting unit 30 and the second pivoting unit 40 so that the first support unit 20 is inclined. The mobile phone 70 is magnetically fixed by the magnetic base 10 so that the user can watch the content played by the mobile phone 70.

[0043] Although the present invention has been described with reference to its preferred embodiments, it will be apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention.
